Building intellij from source - ant build fails on 193.6494.9 and 201.4865.12

I'm trying to compile intellij with changes needed to fix a bug (because the PR hasn't been merged for months now). I've been able to successfully compile the master branch, but it currently has some issues.

I first tried to compile version 193.6494.9 as this is what I've been using at that time, but it kept giving me the following errors:

     [java] cannot find symbol
     [java]   symbol:   class KaptModelBuilderService

As a workaround I built from master and that worked, but due to issues, I wanted to at least try to go back to the last EAP version - 201.4865.12. Which is giving me the following error:

     I did checkout the corresponding tags in android and android/tools-base. I tried both "ant build" and just "ant" commands. I also edited build.xml to give it a bigger heap (otherwise master branch would fail with a GC overhead limit exceeded error).
